I just installed Fedora 17, 64bit on my main laptop, dual booting with Win7 64bit.
The Fedora group didn't make the installation as easy as they could have. You have to manually partition your hard drive. If you have never don't that before, and don't understand sda, sda1, sda2, sda3 or where to install the bootloader. DON'T try it, you'll end up wiping out your hard drive. If you want to try Linux, I would recommend Linux Mint 13 which I posted about here:

I first ran the Fedora 17 live CD to see if the Broadcom wireless driver were included. They haven't been in the past, and you would have to change some script to get them installed, then an update would later wipe them out, and you would have to install them again.
After the installation, there were 88 updates (95MB) including a new kernel 3.3.7-1Fe17 64bit.
So far, so good.
